Code Golf - Banner Generation

Question

When thanking someone, you don't want to just send them an e-mail saying "Thanks!", you want to have something FLASHY:

Input: THANKS!!
Output:
TTT H H AAA N N K K SSS !!! !!! 
 T  H H A A NNN K K S   !!! !!! 
 T  HHH AAA NNN KK  SSS !!! !!! 
 T  H H A A N N K K   S            
 T  H H A A N N K K SSS !!! !!! 

Write a program to generate a banner. You only have to generate upper-case A-Z along with spaces and exclamation points (what is a banner without an exclamation point?). All characters are made up of a 3x5 grid of the same character (so the S is a 3x5 grid made of S). All output should be on one row (so no newlines). Here are all the letters you need:

Input: ABCDEFGHIJKL
Output:
AAA BBB CCC DD  EEE FFF GGG H H III JJJ K K L
A A B B C   D D E   F   G   H H  I    J K K L
AAA BBB C   D D EE  FF  G G HHH  I    J KK  L
A A B B C   D D E   F   G G H H  I  J J K K L
A A BBB CCC DD  EEE F   GGG H H III JJJ K K LLL

Input: MNOPQRSTUVWX
Output:
M M N N OOO PPP QQQ RR  SSS TTT U U V V W W X X
MMM NNN O O P P Q Q R R S    T  U U V V W W  X
M M NNN O O PPP Q Q RR  SSS  T  U U V V WWW  X
M M N N O O P   QQQ R R   S  T  U U V V WWW  X
M M N N OOO P   QQQ R R SSS  T  UUU  V  WWW X X

Input: YZ!
Output:
Y Y ZZZ !!!
Y Y   Z !!!
YYY  Z  !!!
  Y Z
YYY ZZZ !!!

The winner is the shortest source code, as counted by the number of bytes it takes to store the file in utf-8 encoding. Source code should read input from stdin, output to stdout. You can assume input will only contain [A-Z! ]. If you insult the user on incorrect input, you get a 10 character discount =P.

I was going to require these exact 28 characters, but to make it more interesting, you can choose how you want them to look - whatever makes your code shorter! To prove that your letters do look like normal letters, show the output of the last three runs.
